The team needed Boeser to move forward, now they don't have him. You can scratch out some lines to spread our the offence, but it won't work.
In my mind, Pettersson slots right in with Miller. Two centers? too bad. The team needs a pure scoring line line or it's lights out.
I would put Hoglander with them because he knows them both very well.
Put the a line with Lindholm and whoever he feels comfortable with, to try and come up with a second.
